WHAT IS A SINGLE-REPLACEMENT REACTION?

BOOK/OUR DEFINITION:
A Chemical change in which one element replaces a second element in a compound;also called a displacement reaction.

DICTIONARY DEFINITION
A single-displacement reaction, also called single-replacement reaction, is when an element or ion moves out of one compound and into another

WHAT EXACTLY IS A SINGLE-REPLACEMENT REACTION?


In a single replacement reaction, or single displacement reaction, a single uncombined element replaces another in a compound. Two reactants yield two products. The reactivity of a substance depends on its ability to gain or lose electrons it is also known as a Displacement reaction. Ways to predict a single-replacement reaction are by using an activity series, which is a chart that shows which elements would replace other elements in a reaction. It is determined by how high or low the element is on the chart.

Example:

Cu(s) + 2AgNO3(Aq) --> Cu(NO3)2(Aq) + 2Ag(s)







HOW CAN YOU PREDICT THE PRODUCTS OF A SINGLE-REPLACEMENT
REACTION?


The activity series is a way to predict whether or not certain reactions
will occur.Any specific metal can replace any metal listed below it that is in a compound.it cannot replace any metal listed above it.


Example:

Mg + Zn(NO3)2 --> MG(NO3)2 + Zn
